The Archives is open to the public for research every Tuesday and Wednesday, except government holidays, 9 a.m. to 4 p.m.

Please note COVID-19 Update:

The Archives' Reading Room is currently closed until further notice as per New York State guidelines. Please check back often to see if this date is still current, as the situation is always evolving.

If we can assist you by doing the research by mail, we would prefer to do so. We will be evaluating requests on a case-by-case basis.

We encourage you to use our Research By Mail option or, if possible, wait until a later time to continue your research in person.

If you have any questions or concerns, contact us.

The Archives is located at 2199 Saw Mill River Road in Elmsford, New York, and is accessible by major highways, train and bus. Free parking is available. There are no food service facilities on-site, but many reasonably priced delis and restaurants are within easy access by car or bus. The Archives is handicapped accessible.

The Archives' offices are open Monday through Friday, except government holidays, 9 a.m to 5 p.m. Use our Contact Us form for your simple informational questions. However, we cannot answer in-depth queries or requests for records submitted by e-mail or phone. Such research requests require a personal visit, submission of an Individual Record Request form, or the Archives’ staff will conduct Research by Mail for a fee.

Before You Arrive

Take a look at our online indexes and the Guide to the Collections to familiarize yourself with the records in the Archives. Most indexes are alphabetical by last name. Please call first to confirm the hours before you come. You may bring a laptop computer and digital camera into the Reading Room, but all other personal items will be placed in a locker during your visit. Free wi-fi is available to patrons only. 

Please note: If you are planning a group visit the Archives, please view our Groups and Tours Information page.

Reading Room Procedures

On arrival at the Archives, you will enter the Archives Reading Room. You will be asked to fill out a Research Application, review the Reading Room Rules (see below) and show a photo I.D. Return visitors need only show their researcher I.D. card.

All personal items, with the exception of any papers needed for research, are to be placed in a locker. No purses, briefcases, bags or outerwear can be brought into the Reading Room.

The Reading Room is the only room in the Archives accessible to the public. The storage areas are closed to public access for security and preservation purposes. Any materials needed by researchers will be brought to the Reading Room by a staff member or trained volunteer.

Researchers can access two collections in the Reading Room: the County Archives (government records), which includes wills, deeds, naturalizations, maps and photographs; and the library of the Westchester County Historical Society, which includes books and pamphlets on local history, maps, genealogical files, photographs and manuscripts.

You can identify records for use in your research in several ways, by looking through the Guide to the Collections (this can be viewed online before you visit), checking the online indexes, using series and container lists (in binders at the Reading Room Desk), and by looking through the card catalog of the Westchester County Historical Society.

Once you have identified records you wish to see, you will learn how to complete call slips for the materials. You may request up to three items at a time using one call slip per item. Items must be returned to the Reference Desk before new items can be requested.

Archives staff and trained volunteers are on hand at all times to answer questions and help direct your research using both collections.

The Reading Room closes promptly at 4 p.m. Last call slips for materials must be submitted by 3:30 p.m.
